The 23rd First Annual Ig Nobel Prize Ceremony introduced ten new Ig Nobel Prize winners. Each has
done something that makes people laugh then think. The winners traveled to the ceremony, at their own expense, from
several continents. The Prizes were handed to them by a group of genuine, genuinely bemused Nobel Laureates, in Harvard's historic,
largest theater filled with 1100 improbable persons, everything webcast live. The ceremony included many other delights —see
details below. (And For the latest Ig Nobel news, see the blog.)

Live Internet Broadcast

The ceremony was webcast live, here on www.improbable.com and on about 20 major news and science sites. (Here's the
brief teaser.) Here's the full recording:

TOP-SECRET: We provided a second, parallel video feed, as a courtesy to the world's security agencies. Here is
a recording of that NSA Courtesy Cam feed:

[NOTE: This NSA Courtesy Cam video feed went dead part way through the ceremony. Some people have suggested that the
feed was terminated by the NSA; for legal or other reasons we are not commenting on that conjecture]

Webcast Watching Parties

In addition to the many individual Ig Nobel webcast watching parties that happen around the world, there are a few larger,
official ones in Paris, in
Atlanta, in
Raleigh [NC], and many other places.

There was a special party in Leiden, the Netherlands, two days after the ceremony,
with a live performance of the earlier Ig Nobel mini-opera Atom and Eve.)

Groups of five (5) or more persons attending the Ig Nobel prize ceremony can be officially recognized during the ceremony as
Official Delegations. If you would like your group regonized in this way at a future Ig Nobel prize ceremony, first
obtain tickets, then register with Louise Sacco, Official Overseer of the Delegations (phone: 781-690-6621, email: LouiseSacco AT gmail.com).
The deadline for registering as a delegation is a week before the ceremony. These details will be included in the webpage for next year's ceremony.

Downloadable Booklet & Poster

Download your very own PDF copies of the 2013 Ceremony's IgBill (program booklet) and
Spiffy Poster. Both are identical to the ones we print for the ceremony, and
the poster in particular is a great way to increase Ig Nobel and universal awareness among friends, family, colleagues, neighbors,
and complete strangers.

Two grand Paper Airplane Deluges, one at ceremony's beginning, the other at the midpoint

The 24/7 LECTURES, in which several of the world's top thinkers each explained her or his subject twice:FIRST: a complete technical description in TWENTY-FOUR (24) SECONDS*AND THEN: a clear summary that anyone can understand, in SEVEN (7) WORDS

WHAT TO WEAR: We suggest you wear clothing, It's good to wear clothing that is, like you, colorful. People like yourself
(or in some cases, very unlike yourself) in distant places, watching the broadcast and seeing occasional glimpses of the Sanders
Theatre audience, will thrill to the panoply of colors, styles, and improbable accoutrements. This is the night to unearth your old
wedding gown, uniform, suit of armor, labcoat or longjohns.

WHAT TO BRING: Paper, paper, paper. Paper to make into paper airplanes. Additional paper to give to those around you who may have
forgotten to bring their own paper, and who as a consequence of their own neglect are forlornly wishing they could join in the thrill
and intellectual romance of making and throwing paper airplanes. SAFETY FIRST, please! Paper airplanes should be thrown at the
safety-equipment-laden individual onstage who is the Designated Paper Airplane Target. NOTE: There will be two (2) designated Paper
Airplane Deluge periods, one at the very start of the ceremony, the other at the ceremony's midpoint.
